Generating Random Numbers in SQL Server Without Collisions
From time to time, I see a requirement to generate random identifiers for things like users or orders. People want to use random numbers so that the "next" identifier is not guessable, or to prevent insight into how many new users or orders are being generated in a given time frame, but they don't want to run into any duplicates. We can trade a bit of disk space and relatively predictable (but not optimal) performance for the guarantee of no collisions, no matter how many random numbers we've already used.

SSIS 2012 - Introduction to Windows Azure SQL Databases
When discussing SQL Server 2012 Integration Services, we have been dealing mainly with the traditional data management model, where the entire SQL Server environment resides on-premise. This once predominant paradigm is obviously changing, with hosted solutions (in the form of both private and public clouds) becoming increasingly common. In order to properly account for this trend, we turn our attention to the role that SSIS can serve in a mixed environment, where a part of the SQL Server estate is located in Windows Azure.
The Human Cost of Managing Data
There's a cost to managing data that isn't always considered: the human cost. Additional stress, work, and load can result in less than efficient management, even when you contain hard costs.
Manage SQL Server Reporting Services in Management Studio
Most maintenance for SSRS is performed either in Report Manager online or within the Report Services Configuration Manager from the desktop. The SSRS Management Studio connection is certainly no replacement for either of these tools, however, several benefits can be obtained using SSMS. First, you are able to connect to the SSRS even if you are having browser issues; second, it is often quicker to just switch from using Management Studio for the Database Engine.
